Please help us choose some e-books! We are participating in a try-before-you-buy plan for e-books from Elsevier Science. Earlier this year, we deposited $6000 with the vendor to get access to 61 e-books published in 2009. We have access to all of these books through the end of 2011. At the end of 2011, the vendor provides us with data on how much each book was used, and we choose which books to purchase with our $6000. We lose access to books that we don’t purchase.
